US 9,438,608 B2 · Method and device for verifying the integrity of platform software of an electronic device

Abstract

A method for verifying the integrity of platform software of an electronic device is provided, the method comprising accessing a module of said platform software, obtaining a signature (S), obtaining a verification key (VK), said verification key (VK) corresponding to a signing key (SK), verifying if said signature (S) was derived by signing said platform software module with said signing key (SK), by using said verification key (VK), and establishing a positive verification of said platform software module if said verification is successful. The invention also provides a method for providing a platform software module to perform the aforementioned method, and a device on which the aforementioned method can be performed.
